Abstract (en)

[origin: DE4418308A1] A self-crosslinking compsn. contains (a) water; (b) an alkoxysilane contg. perfluoroalkyl gps., of formula Rfa-(A)b-Si(X)(Z)-Y (I); (c) water-soluble-dispersible or -emulsifiable cpds. contg. perfluoroalkyl gps., prepd. from (c1) sulphonamide of formula Rf'-SO2-N(R<1>)-H (II), (c2) cpds. contain oxyethylene units and reactive with 1,2-epoxide gps., (c3) cpds. contg. 1,2-epoxide gps., and opt. (c4) other cpds. with gps. reactive with 1,2-epoxide gps., provided that (c) contains 5-95 wt. % of oxyethylene units, and opt. (d) other components. Rf = 4-20 C monovalent perfluoroalkyl; A = 1-20 C (cyclo)aliphatic, aromatic, and/or heterocyclic gp., with valency (a+1), opt. contg. 1-10 O, S or N atoms; b = 1 or 0; a = 1-4 if b = 1, and a = 1 if b = 0; X, Y, Z = 1-6 C alkoxy with 1-2 O atoms, 6-10 C cycloalkoxy, aryloxy, cycloalkyl or (substd.) aryl, or 1-6 C alkyl, and at least one of these gps. is alkoxy; Rf' = as Rf; and R<1> = H or 1-20 C hydrocarbon chain, opt. broken by 1-4 O atoms.

Abstract (de)

Die vorliegende Erfindung betrifft selbstvernetzende Zubereitungen aus Wasser (A), Perfluoralkylgruppen enthaltenden Alkoxysilanverbindungen (B), Perfluoralkylgruppen enthaltenden, wasserlöslichen oder in Wasser emulgierbaren oder dispergierbaren Verbindungen (C) und gegebenenfalls weiteren Bestandteilen (D), deren Herstellung und Verwendung. Die Komponente C ist erhältlich durch Umsetzung einer Epoxidverbindung mit einem Perfluoralkylsulfonamid und einer Komponente mit Oxyethyleneinheiten und gegenüber Epoxiden reaktiven Gruppen. Bevorzugt wird dabei auch gleichzeitig die Komponente A aus einem glycidylsubstituierten Alkoxysilan und dem Perluoralkylsulfonamid hergestellt. Die Zubereitungen finden Verwendung als Behandlungs-, Schutz- und Imprägniermittel für Glas, Gesteinsmaterialien, Leder, Textilien und Papier.
